BOTTLE.

SPECIFICATION forming part of Letters Patent No. 778,687, dated December 27, 1904.

Application filed July 8, 1904. Serial No. 215,799.

To all whom it may concern.-

Be it known that I, JOHN G. MARMIoN, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have in vented new and useful Improvements in Bottles, of which the following is a specification.

This invention relates to that class of bottles in which the throat is provided with a valve or stopper that operates automatically to allow the pouring of the liquid from the bottle and closes the throat to prevent refilling, which valve or stopper is confined permanently in the bottle-neck, so as to prevent its extraction.

The object of the invention is to so improve this type of bottle as to prevent the confined valve or stopper from closing or partially obstructing the throat during the act of pouring and to effect this provision by a simple, inexpensive, and practical construction.

lVith the above objects in view the invention consists in providing the bottle-neck with an internal valve of resilient nature and in arranging within the neck above the seating position of the valve converging arms or fingers whereby the valve is adapted to be readily forced between said arms or lingers in applying and retained thereby against extraction, while the said valve will be limited thereby in its outward movement to prevent the obstruction of the outward flow of liquid from the bottle.

The invention further consists in certain other novel features in the arrangement and construction of parts, all as hereinafter set forth, and specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure l is a section of a bottle-neck constructed in accordance with the invention and showing the application thereof; Fig. 2, a horizontal section taken on the line w :v of Fig. 1; Fig. 3, a vertical section taken centrally through the stopper.

The neck 1 is formed with the usual throatopening 2 to receive an ordinary stopper should the use of such be desired. The walls of the throat converge downwardly below this opening to form a contracted passage 3, and

below this contraction the walls are expanded and again contracted to form the recess 4 and contracted passage 5, the former being designed to allow the passage of liquid around the valve or stopper 6 when the stopper is dislodged from its seat over the contracted passage 4:.

The valve or stopper 6 is substantially oval in form and tapers slightly toward its lower end in order to readily enter the contracted passage 4L and allow it to be maintained in substantially vertical position at all times, whereby to insure its ready seating. The stopper is formed with a horiZontally-arranged circumferential groove 7, by which is retained a seating-ring 8, of rubber or other elastic material. The main body of the stopper is of a size to admit it to pass readily through the contracted passage 3 when directed longitudinally into said passage; but it will be understood that the said passage is not relied upon solely in the present instance to prevent the extraction of the stopper, and therefore it may be formed of such diameter as to admit the combined stopper-body and ring so readily as not to provide the necessary security to prevent its extraction. In this connection there is used the security device shown, which comprises metal arms or fingers 9, which are disposed so as to lie on the converging walls 10 of the throat in radial arrangement and which extend slightly within the expanded portion l. The upper extremities of these arms or fingers 9 are ,bent downwardly and suitably secured within the bottle-neck, preferably, as shown, by being embedded therein during the manufacture of the bottle; but the same may be permanently fixed by means of cement or in any other suitable manner.

From the foregoing it will be seen that notwithstanding the furthercontraction of the throat made by the arms or fingers 9 the compression of the ring 8 in order to pass them is such as to cause no difficulty in the operation of introducing. this internal stopper, while the resistance offered by the ends of these arms or fingers is such as to cause no compression of the ring that will admit of the withdrawal of the stopper, and the tendency of such resistance will be to still further contract the throat, the lower ends of said arms or fingers being made thereby to approach each other. It will also be seen that during the pouring operation the stopper 6 will come to rest against the arms or fingers, thereby leaving a free passage around the stopper for the outward flow of the liquid.

Having thus described the invention, what is claimed is- 1. A bottle having a tapering upper throatpassage, a contracted lower throat-passage provided with a valve seat, and an expanded portion between said passages, permanentlyfixed spring-fingers supported by the wall of the tapering upper throat-passage and extended downward into said expanded portion, and a valve of oval form having a resilient portion to engage said valve-seat, substantially as described.

2. A bottle having a valve-seat and a superposed guarded throat-passage, and a valve of oval or tapering form having a resilient seating portion at its enlarged end, said valve adapted to be inserted contracted end foremost downward through said. passage and to 2 5 pass the guard through compression of said resilient portion, the latter acting as a support for the inserted valve to engage the valveseat and a stop therefor to engage the guard, and thereby prevent extraction of said valve, 3 substantially as described.

8. A bottle having a downwardly-tapering throat-passage, a valve-seat below the same and an expanded throat-passage between said valve-seat and said tapering throat-passage, a 3 5 valve for said seat and movable in said expanded throat passage, and radial fingers curved to conform to and supported on the walls of the tapering throat-passage and extending within the expanded portion of the 4 throat, substantially as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN G. MARMION.
